Battery Replacement
When replacing batteries, always replace both batteries.
• Turn the selector to “OFF”
• Unsnap the two clips on the side of
the cover that hold the cover in
place.
• Replace both batteries
• Replace the top of the case and
re-secure the clips

The meter should read above the
green marker line. If it does not read
at this level, the batteries are not
charged.
